A sack for realising civil engineering works, including a sack structure with two main faces defined by two respective equal main expanses of cloth that are joined over most of their periphery. The main expanses of cloth define an opening for introducing filling material into the sack structure when in use. The sack comprises at least one expanse of protective cloth whose resistance characteristics differ from the main expanses of cloth. The expanse of protective cloth is fastened to the outside of the sack structure so as to substantially cover a single main face thereof.
